There is a rivercalled the River of No ReturnSometimes it's peacefulAnd sometimes wild and free

A straightforward, scenic and exciting "A" western with the lean, get-in-and-get-the-job-done running time of a "B", River of No Return put major stars Robert Mitchum and Marilyn Monroe together for the first and only time, and the Cinemascope frame can barely contain their combined high-wattage screen presence.

Against the awe-inspiring mountain peaks and wide river valleys of Banff National Park in Alberta, Canada, River opens with widower Matt Calder (Mitchum) - recently released from prison for killing a man - riding into a booming mining camp to collect his nine-year-old son, Mark, who he has arranged to pick up there. He soon finds the boy, wandering around on his ownamid the chaos of the camp.

What's that tag on your coat?

The man who brought me here put it on. I'm looking for my dad.

What's your dad look like?

I don't know. I was just a kid last time I saw him.

Would it be all right if he looked like me?

The boy has struck up a friendship with sultry saloon gal, Kay (Monroe). While Matt takes Mark back to his small cabin and they bond over the hard work of making it a homestead, Kay's no-good gambler boyfriend, Harry (Rory Calhoun) rolls into town. Somehow, Harry's got his hands on a gold mine claim and, with no horses available, he and Kay head off down river on a raft to cash in. Conveniently, they run into trouble on the rapids near Matt and Mark's cabin and are rescued by father and son.

Matt advises Harry to not attempt going any further down the treacherous river. In his desperation to get to his claim in Council City before the original owner can take action, Harry callously repays Matt's hospitality by stealing his horse and rifle. When they scuffle and Harry bludgeons Matt with the rifle butt, Kay refuses to leave the wounded man and his boy alone, so Harry rides off with an empty promise to come back for her.

Defenseless without his rifle, and the river the only means of escape, Matt flees on the raft with Mark and Kay as some Indians close in and burn the cabin to the ground. From then on, Matt's all business, his main goals to keep them alive and exact his revenge on Harry. Kay is equally intent on protecting her tarnished beau. The two do the usual fighting, bickering and slowly burgeoning romance thing, while contending with not only the deadly rapids but attacks from cougars, Indians and rapacious miners on their way to a fateful showdown in Council City...
